@ -1605,10 +1605,9 @@ Rationale: A function or destructor marked
<code>override</code> or <code>final</code> that is
not an override of a base class virtual function will
not compile, and this helps catch common errors. The
specifiers serve as documentation; if no specifier is
present, the reader has to check all ancestors of the
class in question to determine if the function or
destructor is virtual or not.</p>
specifiers serve as a typo check and also as documentation;
you can enforce them by <code>gcc -Wsuggest-override</code>
or <code>clang-tidy -checks=hicpp-use-override</code>.</p>
<p>Multiple inheritance is permitted, but multiple <em>implementation</em>
inheritance is strongly discouraged.</p>
